Subject: [PATCH] erlang-ls: Set `meta.mainProgram`

The erlang language server's primary binary is `erlang_ls`, just like
the repository name, but this package sets the package name to
`erlang-ls` without also either aliasing the binary or setting
`meta.mainProgram`. Setting `meta.mainProgram` to `erlang_ls` should
allow the use of `lib.getExe`.
